some expressiveness is gained, and a creation of a temporary variable
can be avoided.



        ...
        defined $thing and return $thing
        ...

is my working idiom for checking which case makes sense and returning
the first hit.


 when $thing is a complex expression, a temporary variable must be
explicitly
assigned.  "it" holds the place in my pseudocode.

The pseudocode is for a "source filter" so I was thinking syntax
optimizaitons...
